It seems to me that this is a consequence of some really bad design
decisions in TeX !
I have wondered whether the right way to is to make a new variant of
TeX in which there are invisible whatsits (could call them boojums,
perhaps) which are ignored by most of TeX's list-(un)building
activities. For example, a glue-boojum-glue sequence would be treated
as a glue sequence, except that the boojum would remain behind when
the glue was discarded.
Boojum specials would instantly solve the absurd problem of colouring
display maths without screwing up the spacing.
