Well, PROMPT_COMMAND does take shell syntax, so if this is just a
question of getting multiple commands in there, you can separate them
with semicolons.

That said, I do think using an array would be nicer (mainly, it's
easier to manipulate the list of commands programmatically) but then
you can't export the variable any more, for instance.

 Right now, PROMPT_COMMAND gives a shell command to run before
 the prompt. It's common these days to include in one's bash
 numerous packages from different sources that *all* want to run code
 PROMPT_COMMAND time. Can we add a new PROMPT_COMMANDS array variable
 stores a list of shell commands to execute? With a PROMPT_COMMANDS
 variable, different packages can independently add their hooks
 stepping on each other.
