As for me, I changed all my old file names sometime back and have suffered no repercussions. The vast majority of bots/spiders have been shunted over to the newer names.
The logic of specifically naming files to reflect actual words/wording is sound, in my opinion. That, and it makes it much easier to navigate thru the maze of files you now have. Alphabetizing and such.
I did it in my .htacess files with PermanentRedirects and everything is fine.
