Will keep that in mind in the future. Didn't knew people were that paranoid now a days.
Not so much paranoid as more careful, Like
cxx mentioned,
recently some presumed 'leaked' updates were containing some types of malware.
The mods/uploaders here do a great job in trying to catch these before they are put up for download, but it's a cat and mouse thing.
So, it can happen that one slips through due to a new method of hiding and activation delays.
Understandably this makes some folks a bit hesitant in downloading things that are precompiled, and mods don't/can't just scan every post containing an attachment.
The more experienced players probably know how to decompile a precompiled file, but those that don't far outnumber those that do.
That don't mean they will understand what the file does, but at least if the uncompiled form is included or just only that (since it will get compiled at runtime anyways),
it gives a higher sense of trust, since someone wanting to do harm will want to avoid making it easier to detect by not including the uncompiled rpy file(s)
