I understand and agree in general, but surely each change should be
judged by itself, and some, maybe many, might not have these
problematic aspects?

If "server-specific" behavior is, for example, just some non-standard
capabilities, that doesn't count as "server-specific code" in my book.
After all, a standard-compliant server could very well implement only
a subset of the capabilities documented by the standard.

But it should not use advice, IMNSHO.
