Description Alexandre Prokoudine 2017-02-12 12:36:27 UTC 
Some users expect layers to always have an alpha channel.

Now that we have Image Import/Export options in Preferences, how about adding an option to always create a missing alpha channel when importing images?
Comment 1 Michael Natterer 2017-02-12 12:48:23 UTC 
Good idea, and a joke to implement.

Wasn't there some other bug about this?

You're looking for bug 486902 - and bug 762453, which is related or even a duplicate. 

Bug 767177 about (not) being able to paint over transparent areas with some modes might be a precondition to always add an alpha channel vs. having layers without one.

    Add "Add alpha to all layers of imported images" to prefs -> import
    and honor the setting in file_import_image().
