I guess this would neither be necessary nor good. There's a myriad of
tempo mark texts, some (most?) with different meanings w.r.t. the piece
they occur in. You cannot really think about handling all this, and even
if you do, I guess the time for this may better be spent on other
things. Most of the time, you will have to manually adjust the context
settings anyway, and don't gain anything. My two pence...

On the other hand, I could imagine something like a Metronome mark
spanner: (Real-world example for the relevant part; and yup,
"incalzando" has other meanings besides just tempo, but that's not the
point here...)

        \tempo 4 = 76
        c1
        d1\startTempoSpan "incalzando" 4 = 76 4 = 63
        % Start here at tempo 4 = 76
        e1 f1
        g1\stopTempoSpan        % Here, tempo 4 = 63 is reached and kept

The print output probably matches the normal Text spanner, since one
usually wouldn't want to print explicit tempi (at least, this is how
I've handled such things so far, as well as some prints I've seen); but
the semantics clearly are different.
Especially, MIDI output could gradually increase or decrease the speed
without further manual adjustment. That would definitely be a
nice-to-have...

Uh, yeah, and I second the break-align-interface wish there...
