I mentioned to Geoff off-list about possibly using a flush bucket, since I don't have a test setup ready (just replaced my dead laptop hard drive)
Thanks Glenn, calling $r->rflush works perfectly fine to cause user-preset C-L header to be delivered to the client on HEAD request.

I used to make good use of $r->send_http_header() in my MP1 handlers. This method isn't available in MP2 (why?), though I could picture it replaced by sending a flush bucket down the filter chain.

apache now sends the headers for you via the header filter. if you were allowed to send your own headers you might send them before a filter ran that would alter the headers. for instance, mod_include removes the ETag header.
I think this is not the reason why ap_send_http_header was removed from Apache2 API. It's simply not needed because the headers_out filter will inject the headers as soon as some body is sent. Your example of mod_include doesn't work if the response handler does:
$r->print("foo bar"); $r->rflush; # or if the previous print was big enough to cause flush $r->print(q[<!--#include virtual="/foo" -->]);
Would a flush bucket be a great way to say "send headers now"? So if you're not going to send the actual content down the filter chain on a HEAD request, would sending a flush bucket make things happy?
It does.
IIF this works, can I make a request the $r->send_http_header() be implemented in Apache2 to do just that? (create and pass a flush bucket)
Absolutely. But it'd be nice if you could first ask the httpd-dev list: http://httpd.apache.org/lists.html#http-dev if they are interested in adding the C API to do that.
If httpd-dev doesn't do it, I suppose we can still implement it in mp2.
