Nice summary, you should write a My Way about units once this things are fixed.

A few comments from me:

    \type{1234}\tex{unit}\arg{m} should print equivalently to \tex{unit}\arg{1234m}
    and \tex{unit}\arg{1234 m}. (I have a lot of text that uses a \tex{unit}
    macro like that.)

Maybe it’s possible with MkIV to check if the text before the \unit command was
a number but of the number is part of the unit them put in the command, such
things are always tricky with TeX and it’s better to force users to use proper input.

    Within \type{phys-dim.lua} all the units and all the prefixes seem to have
    capitalised names; in fact, they should be all lowercase (even when they
    are named after some person). The exception is Celsius.

I think this is a feature because Hans saves also a lowercase version of all
keywords and you can use both as input.

    I wonder whether \tex{unit} should only parse and format units, and have
    another macro \tex{quan} or \tex{quantity} to handle number+unit combinations
    (obviously using \tex{digit} and \tex{unit}).

Please don’t suggest this, one of the nice features is that you don’t have
to care which command you need but it would be nice to drop the old
formatting options for \digits in the \unit command.
