maybe, maybe not. groups are useful.
They're not used...
if we deprecate the group syntax we will wind up reinventing it.
Perhaps whatever we then invent will be used.
I don't know why groups aren't used. Perhaps it's because people have
little use for the concept, or perhaps there's some detail about their
syntax. In the latter case, a reinvention might succeed where groups
mail receivers should be able to parse groups anyway, since they want
to be able to read legacy messages.
I didn't say the opposite ;)
this proposal strikes me as one of the form: since people won't adhere
to RFC X, presumably because they don't bother to read it fully,
let's write RFC Y that tells them to do something else.
More like "... let's write RFC Y telling other people that they
shouldn't expect anyone to adhere to RFC X".
(Btw, I can think of at least three other reasons why they don't parse
groups, so I don't think that presumption is warranted.)
surely it's harder to read and adhere to the combination of both RFCs
X and Y? particularly when they give conflicting advice?
Specious comparison. People aren't really adhering to RFC X in the first place.
