Well ---if it bothers you so much, I can advise Thomas to forget all about \tiny (not even \relax ing it) and use a new command:

Normal size in 12pt. {\mytinysize This should be in 7pt.} And 12pt again.

Legibility depends sometimes more on the font design than on point size ---I typeset a book with Lucida fonts using 9pt for main text (that is, for \normalsize) with a 30pc text width; whereas 9pt in MinionPro is hardly OK for footnotes. You can't specify a minimum point size in general ---you have to specify minimum point sizes per font family.

A few months back, we had in this list a similar but more annoying problem caused by a bureaucrat ignorant of typography ---the author was told to use 12pt for his text, but said bureaucrat (obviously checking the document with Acrobat) told him it wasn't right ---he was using 11.96pt instead of 12pt! Martin Schröder solved the problem advising the use of bp, instead of pt. As the solution redefines \normalsize, you might not like it :)
