I'm not sure what you consider sane.  They can be combined, but mhl can
only be told a field contains addresses or dates, not both.  And combining
doesn't strip duplicates, e.g. ‘a@b.c’ below.

    $ cat 1
    Date: Sat, 14 May 2022 11:13:58 +0100
    foo: a@b.c, d@e.f
    foo: Sat, 14 May 2022 10:13:58 +0100
    foo: a@b.c, h@h.i
    foo: Sat, 14 May 2022 11:13:58 +0100
    bar: x@y.z
    bar: Sat, 14 May 2022 11:13:59 +0100
    $
    $ cat format
    :Before
    foo:compress,nosplit,overflowoffset=4
    bar:compress,nosplit,overflowoffset=4
    :After
    $
    $ /usr/lib/nmh/mhl -w 72 -form format 1
    Before
    foo: a@b.c, d@e.f Sat, 14 May 2022 10:13:58 +0100 a@b.c, h@h.i Sat, 14
        May 2022 11:13:58 +0100
    bar: x@y.z Sat, 14 May 2022 11:13:59 +0100
    After
    $

If anno(1)'s -append isn't given.
