You'll also find in the help for ft-sh-syntax the sentence:

No need to quote RFCs or market penetration statistics in error
reports, please -- just select the default version of the sh your system
uses in your <.vimrc>.

That's there because posix/ksh users like to quote RFCs about how the
default should be is_posix, and bash users like to quote market
penetration statistics to insist that the default should be is_bash. I
have the Bourne shell as default, not because I particularly like it the
best or anything (I'm a is_kornshell user, myself), but to encourage
users to make an informed choice.

However, please try v117 of sh.vim; it now has some logic using
resolve() to attempt to guess which shell is wanted. It won't be
perfect; for example, what shell should be used with .profile? On my
system, /bin/sh is linked to bash, and so the guessing logic will come
up with setting g:is_bash to one; however, my login shell is ksh, and so
.profile should be interpreted with g:is_kornshell = 1. The guess will
only be made if no g:is_posix, g:is_kornshell, g:is_bash, or g:is_sh exists.

You may get v117 from my website:
