The home directory was not the issue here, the current working
directory was.

I think it has something to do with more usage of Unix/Linux by
non-programmers (to such an extent that they don't even write their
own shell scripts).  They don't benefit from "." in the PATH at all,
so it was removed from the default.  Programmers know how to add it
back.

In the old times, we had "." first in the PATH.  If I am working on a
new version of Gforth, and am in the build directory of Gforth, then
saying "gforth" gives me the development version, not the installed
version.

That had a security disadvantage: If an attacker can get you to unpack
a package, and that package contains, say, an executable "ls", then,
if you are in the directory containing that executable and try to list
the files, you will execute the attacker's executable.

That disadvantage was worked around by removing the "." from the front
and putting it on the back of the PATH.  This allows programmers to
call their programs in the current directory without "./", unless a
version of that program has been installed in another directory in the
PATH.  I guess that, if you have that, you may start to use "./" a
lot, so then you can eliminate "." from the PATH completely.
