Indeed, some commercial stations required the operators use company-provided
bugs with the weights welded on the pendulum to hold the speed down in the
15 WPM range.
The reason was money. More traffic could be handled at 15 WPM than at high
speeds in a given amount of time, thanks to far fewer "fills" needed, and
the ships and their owners were the customers; the last thing a shore
station operator wanted to do was intimidate or irritate a ship's radio
officer.
I've talked with a few guys who talk about how they roared along at high
speeds, but they were operators on some rare, private, closed circuit (often
military) where the same two operators passed traffic to each other day
after day.
I worked a military CW circuit too for the Army in which I worked the same
guy(s) daily and I would get a nasty complaint from the commanders via RTTY
if we got much above 20 WPM even if we were solid copy. They didn't want to
have trouble when a new operator suddenly sat down at one end. Soldiers must
be fully interchangeable. That's what G.I. (government issue) means when
applied to the military.
Smart commercial operations are that way too. The *last* thing they want is
to have their profit and performance dependent upon a few hard-to-replace
people.

Many believe that marine radiotelegraphy back in the "good old days" was
moderately high speed. In fact, it wasn't at all. We ran our wheel at
18WPM which is what W1AW uses for bulletins I think. All the operator
afloat had to be able to copy was our and his call signs. He could look
the QSX up. Traffic was essentially always handled slower ... 15WPM or
below. Press was normally sent at 18-20, it didn't require letter
perfect copy. Fists afloat ranged from pretty good to totally awful.
Vibroplexes were notoriously hard to slow down to the common speeds.
See radiomarine.org/historic-5.html for one ingenious example.
50WPM is fast enough for me.
