Seems like SYS_LASTCHANGE is not designed very clever. Hm, I will have a
closer look at the code. The perfect way would be if *any* content
element of a page will trigger neccessary updates of pages.SYS_LASTCHANGE.

Something like
TCEMAIN.updateSYSLASTCHANGEcmd = [pid]

As this seems to be a general problem of any extension, it should be
part of the core.

I mean HTTP caching headers, rendered by tslib_fe::sendCacheHeaders [1]
The "Last modified" field depends on SYS_LASTCHANGE and it is not going
to be changed, if the cache of a page is cleared (and rebuild).
