            (Is pdftex to be deprecated and replaced by luatex?

No, pdftex is not and will not be "deprecated". Both will continue to
exist for the foreseeable future. People who like/need luatex can use it.
There is no problem there.

For typesetting normal documents, i.e., almost everything, the
conventional limits of the other TeX engines are not an issue. -k
