No, this is not the right description for the development process. In
fact, such implementation details are revised over time and usually
discussed on the TDS mailing list before they are implemented. It is
just a matter of timing whether a stand-alone web2c distribution or TeX
Live or teTeX is the first release implementing something new.

The kpathsea library provides an API to locate files along different
omega specific search paths, e.g. kpse_otp_format. The implementation
needs to be changed to access OTP files only via these search formats.

Some omega is quite useless in teTeX-3.0. Interestingly, I did not get
a single bug report about it. Where are the users of omega? What binaries
are they using? Is none of them using teTeX?

The TDS working group has decided against the engine specific separation.
I think that you should raise your issues there, but I also suggest
that you search the list archives for thediscussion that has led to

That file can be in a format specific subdirectory in tex/. The version
in tex/generic will then be used for all formats which don't have their
own file *and* sarch path.

TDS-1.1 and the engines (omega, aleph etc.) should be fixed.
