That's also the behaviour of globbing in the  fish shell.

That means that for instance you cannot match dot files (or any
pattern matching on the beggining of the file in fish.

For zsh's **/.*, in fish you'd need both .* and **/.*

I prefer zsh behaviour.

ksh93, bash and tcsh support ** alone, but not **.c

BTW, a related question:

In zsh (also in yash and tcsh now), *** is the version of **
that traverses symlinks.

Also,

*.d/foo

traverses symlinks,

(*.d)#/foo

doesn't

** is short for (*/)#

Is there a way to do */foo without traversing symlinks (other
than l=(*(/N)); l=($^l/foo(N)); (($#l)) && cmd $l)?

(*/)(#c1)foo doesn't work

Or (^.svn/)#foo.c that traverses symlinks?
