In French, you always need an article in front of a group including an adjective, and that rule applies to professions:
Paul est un professeur extraordinaire.
Otherwise: Paul est professeur. (note: no adjective, hence no article)

Is this becoming obsolete in actual practice, like in English?

Bonjour David,
Not at all, quite the contrary. French is moving toward creating feminine forms for nouns that are currently masculine only, such as un pompier, which now has a feminine counterpart une pompière. There's some debate about whether this is necessary / desirable, but it's certainly not going obsolete.
