IMO, that means someone is doing things wrong. But yeah they probably won't agree;-(
Basically, it easier to just support all the combos than to support some fixed list of ciphersuites.And from experience implementing HPKE: The various non-base modes aremuch more annoying than all the KEM/KDF/AEAD combos.
90 suites and 4 modes is a silly amount of combinations, yes, esp since afaik all protocols so far only use base mode etc. Cheers, s.
