I want to write extension E1 and need to load the TCA of table T1 my plugin 
P1. I should be able to load the TCA via a call, but I currently can only 
do this by loading the complete TCA. A waste of resource, but no show stopper.

To avoid this Franz seriously suggests, that I have to list all extensions 
E2 to EN which I - the deveolper!!!! - know to modify the table T1. Sorry, 
but this is rubbish.

Any plugin must be able to load the TCA without such external knowledge. I 
have suggested a better scheme, but there might be others. The point is, if 
anyone has to track which extensions modifies a table then it is the EM. *

But even then I don't think it should be done on a per-extension basis. We 
should find a clever way to get only parts of the TCA **, but the presented 
function definitely is not the way.

* There is already such knowledege about the table itself (added columns), 
but not of subtle changes of the TCA.

** I sometimes wonder if the clever way of configuring by PHP allows too 
much flexibility instead of a text/xml configuration.
