False.

Your MLM rules impose a global syntax and global semantics. Whenever one
of your ``subaddress aware'' MLMs accepts bob+ruth@absolutely.anywhere,
it is also required to accept bob+liz.

This global scheme is incompatible with existing addresses. Your MLM
requirement is a security violation.

Mm-hm. Where exactly is your response to the widget-request problem?

Just to refresh your memory: There's a group project account called
widget. ``widget'' is also the mailing list for that project, run by
some MLM.

Most separators are incompatible with the de facto ``-request''
standard. If "+" is the separator, for example, the widget people will
end up pestering the sysadmin for a special ``widget-request'' alias.

With "-" as the subaddress separator, the widget account automatically
controls ``widget-request'', as well as ``widget-owner'' and
``widget-subscribe'' and whatever other addresses the MLM might support.
This is clearly superior.

Getting you to admit that the right address is ``widget-request'' and
not ``widget+request'' was like pulling teeth; I had to ask three times.
Apparently you don't want to admit any benefits of "-". You've spent far
more time claiming, incorrectly, that "-" doesn't work.

False. Many qmail sysadmins use this convention. There is no conflict.

For example, if there are jean and jean-pierre.serre accounts, the
jean-pierre.serre account controls jean-pierre.serre-books-request.
(UNIX traditionally doesn't support such long account names, but qmail
supports a translation table: e.g., jps:jean-pierre.serre.)

Similarly, if + is the separator, and there are smith and smith+co
accounts, the address smith+co+help is controlled by smith+co.

Next strawman?
