Possibly, but if you are not proposing to do that, then nobody is, I think.
I think it would be overdoing it just a little.

How is 27-35 interpreted now?
Would it alter the evaluation of this value if you would e.g. specify that
a suffix (2) may be added to a housenumber string  to indicate that it is a
range with increment 2?
Would it alter the evaluation if e.g. single quoting  was an added option
to force interpretation as a single housenumber, rather than a range?
You see, if it is ambiguous now, it remains ambiguous even if these options
were there. If one data user interprets it one way, another the other way,
and the third just ignores it, you lose nothing by adding the options.
Nothing is lost by not using extra options, but you may gain something by
adding them.

So, let's not go there.  Let's go for extra's that add something if
applied, without demanding retagging of existing data.
