with the relative tempo changes I'm working on I see only the usecase to

Moreover, this usecase is limited to the 'working score', in the score
one is going to publish I expect this will be removed (e.g. by tag).
And yes, I've seen metronome marks with one decimal only in printed
sheet music (using typical classical notation) by Karlheinz Stockhausen
until now.
The default formatting is appropriate for music of a certain era and
there are facilities to override the defaults.
There was a short discussion a while ago about packaging an alternative
formatter with LilyPond, but it was all at this same level of confidence
("I've seen", "I'm aware of") rather than citing specific examples.

My instinct is that a context property specifying the range of decimal
places to print (at least N, no more than M) would serve the purpose,
but it might be unnecessarily complicated. Maybe it would be better
just to provide an alternative formatter that prints the fractional part
to its limit and leaves off trailing zeros.
It would be best to work from published examples. For example, it would
be nice to know whether Stockhausen ever specified a tempo with a
trailing zero, e.g., 70.0.
