the problem of this method is that it might override definitions of
other plugins because it resets the whole '"tx_xxxx"'

That method is safe *only* for your own extensions,
which don't modify *existing* tables.

if you want to modify existing tables

t3lib_div::loadTCA("existing_table");

and then define *only* necessary parts, for example
$TCA['existing_table']['columns']['title']['label']=...
