Well, I wouldn't count on there being a solution for what you're asking, in the next version. This has been requested for a long, long time, and I stopped holding my breath a long time ago! You should probably download the development version, and test it, to be sure. If you get the right dev version, you won't have to worry about crashes or broken things. (I mean, if developers want people to test it, there has to be at least one version which works fairly dependably.)
Unfortunately, I can't tell you which version is the one you want. The last time I looked at the site or repo where they are kept, I couldn't decipher any of it. So therefore, I didn't save a link to it....I don't think.... Well actually, this might be it:
https://ci.appveyor.com/project/inkscape/inkscape/historyThat is an interesting thought - to remove all the other extensions except the one you want. I guess if everyone uses only that program, and only for that one purpose....I don't know why it wouldn't work. However, I've never heard of it being done before.
For myself, a lot of the files in that directory have odd names (well, to me they are odd), and I would worry that I might remove one which should remain. But I guess as long as you are careful, and you're not deleting things, but saving or moving them somewhere else, it would be worth a try. It looks like it has some files which make the Help menu work..... I don't know, maybe Moini would know what to remove and what to keep?
