they already made that.
but the problem is - when you download it it still doesn't install automatically, you don't have a plugin manager that has everything you have installed + uninstall options, you can't choose versions, and so on.. it doesn't report bugs to developer automatically, and doesn't have comment section on it's own. also no versioning.
with this you could open a ticket, write and attach capx and bam - posted to developer. he can then download your capx and see the text, while others will only be able to see text without capx (for copyrighted work).
