I don't see how a LaTeX package should be the beneficiary of anything.
The beneficiaries of the proposed change are LaTeX users who want to use
the microtypographic extensions provided by pdfTeX for DVI output or
especially parallel DVI and PDF output.

I was a bit too optimistic here. As Frank correctly mentioned in his
reply to your message, microtype.sty not only differentiates between DVI
and PDF output, but also between different versions of pdfTeX. This is
necessary since the microtypographic extensions provided by pdfTeX have
changed over the time. It /might/ be possible to adapt microtype.sty to
the primitive-masking in TeX Live 2004, but it sounds very error-prone.
Please not that the reason for building the LaTeX format using pdfTeX
was to enable the microtypographic extensions for DVI output, too. It
now has been realized that masking some of the new primitves provided by
pdfTeX inhibits to a large degree the very purpose of the original
change. Hence, either go back to using eTeX for the LaTeX format or use
an uncrippled pdfTeX.

Relax, this does not concern the TeX lion at all. We are talking about
the LaTeX format here. The plain TeX format is still produced using 'TeX
the program' without any extensions.
