Yes, it does for me with version 2.2.3.
It is documented for 1.3 too ...
.... somehow I've skipped that page for over 7 years in a row

The rewritemap would return 'Default Value' for LookupKeys not listed.
Defaulting is part of your question and this single directive justs gets
closest.

You cannt use rewritemap in .htaccess ...

It is my understanding your hoster is providing you ONE WILDCARD domain on a
shared host and you are attempting to virtualize that for some subdomains.

Try
RewriteRule ^/(.*)$ /yourscript.pqr?site=%{ENV:site}&request=$1 [QSA,PT]

Even then isolation may come in handy for images, stylesheets and
javasripts.
To use a single script accros all subdomains have subs/pages/.htacces and
www/pages/.htaccess rewrite the request to that script:
RewriteRule ^.*/(.*)$
%{DOCUMENT_ROOT}/../yourscript.pqr?site=%{ENV:site}&request=$1 [QSA,PT]

If your need to change, just modify one of the */pages/.htaccess to have
that one sub domain use another script.
