For a single QID does it make sense to use a HTTP HEAD request against the
item page? I assume it would perform well on the client at least.

You can do this via the API, e.g.:
https://www.wikidata.org/w/api.php?action=query&prop=&
format=json&titles=Q1|Qx|Q10000003|Q66666666666666&redirects=1
Note that this uses QIDs directy as page titles. This works on wikidata,
but may
not work on all wikibase instances. It also does not work for PIDs: for
these,
you have to prefix the Property namespace, as in Property:P31.
A more wikibase way would be to use the wbgetentities API, as in
https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42|Q64&…
However, this API fails when you proivde a non-existing ID, without
providing
any information about other IDs. So you can quickly check if all the IDs
you
have are ok, but you may need several calls to get a list of all the bad
IDs.
That's rather annoying for your use case. Feel free to file a ticket on
phabricator.wikimedia.org. Use the wikidata tag. Tahnks!
