So in the example I gave, I think you're proposing that
addr:flats=11-12;25-28;41-44;51-54 should become addr:flats=Flat 11- Flat
12;Flat 25- Flat 28;Flat 41- Flat 44;Flat 51- Flat 54. I really don't like
this:
1) Repetition and redundancy;
2) None of the current 13,000+ UK tags
<https://taginfo.openstreetmap.org.uk/keys/addr:flats#overview> are
currently like this as far as I can see;
3) In its current form, a fairly simple function can parse tag values like
this to determine the number of flats - this is what I use it for. Adding
in a designator word before each number/letter in ranges would really
complicate it.

I suggest either:

   - a separate tag, possibly 'addr:unit_designator', maybe with a default
   value if absent eg "Flat"
   - prefixing the addr:unit/flats value before a (say) colon - ie
   addr:flats=Flat:11-12;25-28;41-44;51-54 (I'm less keen on this idea)
