Well,
1) It clearly wouldn't be difficult for them to do this, or even to integrate it with the existing Docs editor. The Docs editor can already view them, in fact, so it's kind of baffling why they stopped short of editing.
2) It would be preferable for both usability and performance to have it integrated with Drive rather than as an external app.
3) The Android Drive app can already edit text files.
1) It might not be difficult, but that doesn't mean they should do it. I don't really think it's "baffling" why they wouldn't build a bunch of extra functionality that probably wouldn't be used by many people. Most people editing documents want a wysiwyg editor like Google Docs, from which they can always download the file in the plain text format. People who actually edit plain text files regularly (programmers and such) probably have a preferred editor that they use, and wouldn't really want to edit in a little <textarea>, unless you are proposing they build a more advanced text editor (I assume that's not what you mean though, you said it wouldn't be difficult).
2) Sure, but again, just because they can add a feature doesn't mean they should.
3) Interesting, I didn't know that. Maybe they are planning to add the feature after all.
Another option of course is to use the Google Drive desktop program, and edit your plain text files locally, which will be synced to your Drive.

As mentioned elsewhere in this thread, the Google Drive desktop syncers leave quite a bit to be desired. I've used both the Mac and the Windows version. The Windows version crashes regularly, and the Mac version racks up sizable memory leaks after a few days of use. They both use more disk and CPU resources than it seems like they should need, too. At least they aren't as bad as the Google Music desktop client, though.
I'd love to see Google Drive fleshed out this way. And even if not with a video editor, at least a viewing tool for video. And a better one for images. (Though, obviously editing tools would be nice.)
Similarly, I'd like the ability to view (and download/upload) my Google Music files in a Drive style. You know, while I'm dreaming.
