find: print trailing slash for directories

Hello,

how difficult would it be to patch find, to print trailing slash for
directories?

This seems like a very useful feature, without interfering with
compatibility or specifications.

I have found many questions on the various forums. There are some ugly
hacks offered, all relying on piping find output to other commands (sed).

The least ugly one I found: find . -printf "%p:%y\n"

I am wondering if some simple patch would be possible to do this by
default in find?

I am using findutils 4.6.0 on Debian 10

I would be happy to patch my own find, if somebody could kindly offer a
solution. I am not a programmer myself, just a sysadmin.

thank you
