I observe that as of bash 5.3, the bash(1) manpage says[^1]:

    Command Substitution
        Command substitution allows the output of a command to replace 
the command itself.  There are two standard forms:

               $(command)
        or (deprecated)
               `command`.

It also refers to "the old-style backquote form of substitution".  But 
why they decided to deprecate traditional / standard usage is unclear.
