You are right that <domain $hotmail.$TLD> would create many queues connecting to different MXs. That could results in 10+ queues all connecting to the same MX, like hotmail.de,hotmail.es,hotmail.fr,hotmail.it, hotmail.se which all use hotmail.com's mx records and potentially flood the same mx with too many connections.
You can avoid this by using a domain macro that matches all Hotmail/Outlook domains and then uses "queue-to" to roll them into a singe queue (<domain> directive). It's ideal to have all these domains rolled into one queue, so you have more control over how many connections they are collectively opening to the mx at hotmail.com which are shared by many domains, rather than having 10-20 independent queues all connecting to the same MX and possibly overloading it. When using "queue-to", "Use of the route directive is required." per the pmta manual. The "route" directive forces all those domains in the macro to use one static MX record. So, yes, with that setup all Hotmail/Outlook domains get rolled into one fixed MX record, with "route hotmail.com" or whatever domain you choose. If you were to ditch the "queue-to" directive and just use something like you suggested: <domain $hotmail.$TLD> that would potentially open too many queues to the same MX's and at times overload them with too many connections? Or maybe with Hotmail/Outlook's new setup of unique MX's for each domain, this doesn't matter anymore? Maybe this thread belongs in the PMTA Forums instead.
