To drop another n=4 anecdote, yes, all places I worked in were more-less like that.

(One reason why I dislike the terms like "professional software $something" or "industry standard" is because while they connote quality, they're defined by "as done by people who are paid to do this" and "the popular thing among people who get paid for this work", respectively. The two viewpoints - quality vs. what professionals do - are almost completely opposite in practice, given the shit show our industry is.)
