The problem with the 61 is not necessarily itself, its just that its an oddball thats often mistaken for the D60 but isn't, so if you buy a set of gears for a D60, it won't fit the D60. I forget what is all different, but I just remember hearing my partsmen talking about it.

Was there ever a semi-floating D60?

Yeah, there were semi-floating Dana 60s. In fact a lot of the big block and Hemi MOPAR muscle cars had them.
Ford used them in trucks from '67-'69 in F-100s and again from '80-'85 in F-250s but NOT diesels. It was known as a 60-2.

The Dana 61 was made for Ford starting in'74 so they could have higher gear ratios for fuel economy reasons. A std. Dana 60 can only have a ratio as high as 3:31. The pinion off-set was increased 7/16 to accomidate the higher gears. It was also available as a semi-floater.
For a while now you have been able to get the "thick" gear sets to change the ratio all the way up to at least 4:10s. As a bit of trivia I think this is the ONLY 60/70/80 series Dana axle that you can get 4:11 gears for (Yukon Gear) everything else is 4:10s.

The full floater is a 61-1
semi floater 61-2

Dodge also used front 61s in MOST of the first Cummins powered trucks. Since they had no over drive trans. until '91 in the diesels they used 3:07 gears.
This combination actually works really well with a diesel's low-end torque. Ask the 2wd Ford diesel guys with 3:07s and they'll usually tell you the same thing.

It's virtually the same as the 60 except for the pinion off-set.
