Thanks for clarifying! I wondered if I was missing something, but kept seeing
`${BASH_SOURCE[0]/%/*}` suggested in the thread, which I pointed out is flawed.
I guess what I want is a "BASH_SOURCE_DIR" variable or something like it,
mainly to avoid the boilerplate, variable, and/or command substitution in each
of my main scripts.
Note that ShellCheck uses a similar SCRIPTDIR to help locate sourced files
relative to the main script:

I agree.

You misunderstood the use of BASH_SOURCE_PATH though. It's proposed
to be an alternative to PATH which is only respected by source. I
suggest another name. And that is BASH_SOURCE_REAL.
Alternatively, have BASH_SOURCE always produce real physical paths
either by default or through a shopt.
Any additional feature that doesn't allow loading a script relative to
the caller without external help is practically useless.
