I have a tele/macro "eye", but that doesn't mean I don't use WA. I just
shot some with 19mm on the 5D a few days ago.

Your calculations are all correct, as far as I know. But I also wanted
my Zuiko WAs to be WA and for my favorite zoom to go down to 28mm. Not
buying a small sensor zoom for the 30D was one part of the cost
justification for the 5D. I'll probably get a Tam 17-35/2.8-4 one day,
but I've done fine without so far.
So my thinking was that I wanted the 5D for several reasons, but was
concerned about losing the 500 mm reach I had grown used to and loved
with the 300D. So starting with the decision that the 6 mp 300D was
doing a fine job with tele, I thought I could have my 5D cake and be no
worse off with a cropped image to give 500 mm eq. than I already was. As
it turns out, the central 5mp of the 5D resolves more than the 6.3 mp of
the 300D, so I won.
On the 30D, the Tammy is 45-480 eq., On the 5D, assuming that 5 mp is
acceptable, it is 28-480, so I don't need another lens for many more
shots. Also, the Tammy is pretty good, but I'm not sure that the higher
resolution needed for the 30D sensor will be there, not just at the long
end, but in general. So I might get better results with the FF sensor
due to lens limits. Using your numbers, I only need 64 lpm at 160 mm on
the 5D, but need 82 lpm at 100 mm for the same shot with the 30D And
there are other reasons to prefer the 5D, so I went that way.
No regrets either, what a wonderful image maker.
