Perhaps you were referring to the fact that --regex- in ctags is more different than --regex in etags, not just because it puts LANG in the flag name rather than inside the value. It also allows specifying regexp syntax, and defaults to extended RE. That is indeed problematic, and not so trivial to implement in a compatibility layer.
