Maybe european decimal points slide off drawings and fall on the
floor. Robust American decimal points and schematic connect dots don't
do that.

I wasn't aware that there was a difference between European and american

There is a difference between English-speking ones and French-speaking
ones: the French ones look like commas.

Do French engineers use the same convention on their schematics?

I don't know, but the comma is in everyday use as a decimal point.

I can't recall ever seeing a French schematic, actually.

I can - and it was dreadful !  It was of a laboratory R.F. signal
generator and they had put the earthing point in the centre with the
various sections of the circuit radiating like the spokes of a wheel
around it.  The HT line ran around the outside.

There are people, even gigabuck organizations, who are obsessed with

Decoupling capacitors such as 0.1uF everywhere can also be an obsession.
Remove them from many (not all) circuits with no change in performance.

I knew one guy that claimed that bypass caps weren't necessary on
multilayer boards. His stuff worked.

Most electronics is way over-bypassed. Every data sheet assumes that
their part is the center of the universe and deserves a string of
stepped-value bypass caps on every supply.
