...and if I had to choose between the two evils, I'd rather be closer to
'everything is optional' because failing against servers that don't provide
what you need is natural selection; whereas clients typically cannot cope
with missing-bits of claimed support ("as described on page three of the
readme file")  [and I may have a closer affinity with server developers
