Of course, but that has not very much to do with your statement that
it is a "cheap bodge" to paint over old gloss. It isn't in the large
majority of cases. Your 100 y.o. architrave probably looked fine
intil about 1975.

I'm just used to houses built around 1880-1910. They ALL have/had blobby
mess architraves. Even my "old" 1986 built hutch had issues with overpainted
gloss, with the crevices looking less than sharp.
