Ah, that is a good question.
I think it's all about taste.
Some guys here have a vintage dial, modified, with lume at night, some don't.
To me, sorry to say, it is a total non sense to have lume at night on a 30, 40, 50 years old watch.
The lume material used in those days should not last that long.
If you take a 16800 from 1980 in example with a mate tritium dial it has no lume at all anymore today.
So my humble opinion is: vintage => no lume
