systemd.service(5) reads, in the section about ExecStart=:
Basic environment variable substitution is supported.
Use "${FOO}" as part of a word, or as a word of its own, on
the command line, in which case it will be replaced by the
value of the environment variable including all whitespace
it contains, resulting in a single argument. Use "$FOO" as
a separate word on the command line, in which case it will
be replaced by the value of the environment variable split
at whitespace, resulting in zero or more arguments. To pass
a literal dollar sign, use "$$". Variables whose value is
not known at expansion time are treated as empty strings.
Note that the first argument (i.e. the program to execute)
may not be a variable.
Isn't it enough?
Cheers,
