Actually, even shorter:
If your source and destination are layers on the same image:
1) On the Layers Toolbox: hide the layer you want to apply the Alpha Channel to.
2) On the Channels Toolbox: right click on your Alpha Channel.
3) Select "Channel to Selection"
4) On the Layers Toolbox: right click on your hidden layer.
5) Select "Add Layer Mask" from the context menu.
6) Choose "Selection" as the Initialization Source.

1) On the Layers Toolbox: right click on your canvas layer.
2) Select "Add Layer Mask" from the context menu.
3) Choose "Layer's Alpha Channel" as the Initialization Source.
4) Copy your image. [You are in "Edit Layer Mask" mode now, so it copy the mask data].
Transfer Alpha Channel [to a new image]:
1) On the Layers Toolbox: right click on your canvas layer.
2) Select "Add Layer Mask" from the context menu.
3) Choose "White" as the Initialization Source.
4) Paste [it will create a Floating Layer.].
5) Click the "Anchor the Floating Layer" icon on the Layers Toolbox. [Which makes the Floating Layer the new Source for your mask. This will work with any image source, not just Masks copied using the prior instructions.]
[Optional]
6) On the Layers Toolbox: right click on your canvas layer.
7) Select "Apply Layer Mask". [Will merge the Mask with the Alpha Channel; removing the Mask.]
Personally, I would stick to keeping the transparency data in Mask form for the rest of your workflow. Once you export your image as a PNG [or any format with Alpha support], GIMP will automatically apply the Mask for you.

I use GIMP on Windows 10 at work on a Intel Core i7 "Skylake", I think it is a 6700T.
I don't know how long it takes to launch, but its definitely less than a minute. Probably between 10 to 30 seconds.

One thing I really miss in GIMP is easy access to a PNG alpha channel, specifically copy/paste the alpha channel between two images. I think it's at least 10 clicks and some drag operations to select things, saving/loading temporary files. I always seem to get lost along the way, forget how it works, or do things in the wrong order. Extremely cumbersome for such a simple operation.
In Corel PhotoPaint 7 (released 1999, which I still use almost daily) it is only 2 toolbar button clicks ('display alpha', 'copy')!
That said, even in Adobe PhotoShop it is (was?) many more than 2 clicks. Either way, working with transparent PNGs in PS or GIMP really suffers from poor workflow. Which is probably why I still use a 20 year old closed source product (though running nearly flawlessly on Wine - and fast and feature-complete!).
I like where GIMP is going, but it still has some catching up to do, especially on the UI/workflow front...unfortunately that's also the area where controversy arises, and people start having diverging opinions. Perhaps there's lessons to take from Blender, where they are finally making substantial improvements on the UI front, after many years of indecision.

This is mainly a Linux forum, but we discuss other operating systems as well.

Also hate Windows as much as you want, but GIMP is already available for Windows, so if it could be available in the Windows Store and that could lead to new users discovering it, and new revenue streams, then that would be great.

Actually, I'm wondering how much time and effort it took to get Krita to work on UWP.

Personally, I would like to use our funds to get people to work on GIMP full-time. But it means there will have to be a full-time paid manager as well. We don't have one either.
