Also, Python is the only ecosystem I know of where people actually get angry that you use an old and stable version of the software, as those downvotes indicate.
Python might be an especially loud case, but I've seen a fair amount of that in some other areas, for example:
- People getting angry at browser JS authors for coding in explicit support, or huge back-compat shims, for obsolete browsers and/or deprecated JS features.
- People getting angry at Perl authors for writing code that depends on a stable hash iteration order (changed in Perl 5.26 or something? I forget). There was an extremely vocal (tiny) minority of users raising a big stink about the change in that behavior and claiming that it would break the universe.
- C developers being criticized for coding to older (and often more verbose or tricky to use, but omnipresent) pure-POSIX macros and behavior rather than $latest_GNU_or_GCC_feature, which also had the pernicious effect of making things less portable, and damaging the culture of portability.
