I can see how it might make sense to use OSC as a proxy protocol
between MIDI devices. Other than that, I don't see the point of
restricting oneself to MIDI while using OSC.

Although [packOSC] and [oscformat] do not directly support the m tag,
you could still cook your own format using 'b' (blob) type and four
bytes. And if you really need it to be proper 'm', you could still
write it as an abstraction (as long as it supports only one tag, it
should be fairly simple with [list tosymbol] and some [list append]s
and [list prepend]s).
