we are still sitting on 4.5 but the following things should apply to 6.2 and above:
Please consider adding the following hooks:
Additional Mail Markers
We would like to load a signature with an additional marker. On 4.5 XCLASS'ing doesn't seem to work although a XCLASS definition exist it doesn't load the classes at all places.
The existing hook $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkvalidator']['checkLinks'] isn't helpful imho.
You need to rewrite everything if you want to support TV - FCE's for example. But in fact 80-90% of the existing code could be reused if you would add a hook at the end of analyzeRecord() that would pass all values. Other than that you would only have to change the visibility to public for analyseLinks() and analyseTypoLinks(). With that its possible to use the existing validation code for flexforms and probably many more.

For point 2.) Yes, that's true, this is really annoying, I needed to XCLass the LinkValidator to make this functions available in public.
As you are speaking of TV - FCEs, I put this into an extension. See https://extensions.typo3.org/extension/ppi_tvplus_linkvalidator/
If this extension is fine for you, I'd like to close this issue and create 2 dedicated issues for your point 1 and 2 (as they are independent and every problem should have his own issue number to resolve too).
