I thought that an encoding describes only the mapping of a number to a
glyph. Isn't this true?
If ligatures are part of an encoding, then all the sources I know that
claim to describe T1 (or LY1, or AdobeStandard) are at least incomplete.

For use with T1?

I am curious: cmr, cmtt, cmmi, cmsy, cmex?
But the last three are math encodings (more or less ;-))
Maybe it would be a good idea, to have subdivisons for (TeX) encodings?
The the problem would vanish to having T1(.normal) and T1.tt that only
differ in the used ligatures ...
