IIRC latest posix includes $(command) as well.
It is definitely *not* a bashism, given that it is supported by POSIX. It is supported by all POSIX shells, and this does include dash. You should definitely use $() in place of backticks where possible, and portability concerns are unwarranted here given that all real shells include support for it. posh is an exception, but is not a POSIX shell since it does not support this POSIX feature.
