I'd tend to just ignore anyone that uses the word 'bloat' without backing their statement up with any substance/insight or perhaps acknowledgement that they may be wrong on some counts and are unlikely to understand the entire problem-space of said project to the extent they can justify deeming any significant portion of it unnecessary.
Well sure, but maybe he has genuine and interesting issues with Python 3, and maybe he just had a bad day, hasn't had his coffee yet or whatever and went with a quip rather than a complete comment. That happens.
Sure, but it's lazy either way. Cries of 'bloat' without some supporting reasoning = alarms bells suggesting willful ignorance to me.
Personally gets my goat a lot at work. It's so easy to allude to bloat, or (for example) some framework containing 'stuff you don't need' instead of doing your homework and making an effort to understand why that stuff exists.
I can't make head or tail of that claim, what's the "bloat since 3.0"?
