I got several soft rejections because the problem with prefixes here is the last:
Prefix everything and use unique (theme-name-based) consistent slugs. Additional prefix is acceptable for when the author is using a framework.
Avoid using initials or abbreviations.
Here’s a list of the most common things that should be prefixed: PHP function names, PHP class names, PHP global variables, Action/Filter hooks, Script handles, Style handles and Image size names.
