This is done by generic printing routine 'sayKeyedMsg' (in msgdb.boot)
which calls 'prefix2String' (in format.boot) which in turn uses
'form2String1'. 'form2String1' calls 'formArguments2String' to handle
arguments.

One possibility: add a buch of global flags, check them in 'form2String1'
and 'formArguments2String' to decide if shorter form is desirable.
A bit tricky because 'form2String1' is used by 'unparse' which is
supposed to produce string equivalent of expression (which means that
'unparse' is not allowed to omit part of output).
Another: add a special-purpose routine for shortcut formatting of
types. Call it from 'printTypeAndTimeNormal' (and possibly other
places which use '$printTypeIfTrue').
How shortcut form of types should look like is another matter.
It would be easy to limit output to top constructor, for example
to have just 'DistributedMultivariatePolynomial' without
parameters (or just DMP). Or if type matches expansion of a macro
we could replace it by macro name. Or maybe truncate at given
character length.
