% is the value shown on signs, the highest I can remember seeing is 25%, will be on the lookout now.
There may still be some older 1:4 (1 in 4) type signs around so maybe a unit is useful.

My apologies if it was my post that got this off track.   

I think the original point was, if "%" is the default "unit", should we actually be putting the "%" in the tag?   

My view is that it is not required, but putting it in causes little harm. 
While trying hard to be non technical, % is not a unit (dimension) but a multiplier.
In km, m is the unit (meter) and k is the multiplier (1000).
In "%" there is no unit and the multiplier is .01.
My snippy comment means that many people seeing "10" would ask "10 what?".
A dimensionless value is disturbing and that's why people like to keep something with %.
So, why remove what doesn't hurt indeed, is self-describing and that everybody understands?
It ain't broke ! ;-)

For technical people, a 10% slope is .10 and a school mark is between 0 and 1.

But I see that several of us are writing the same thing at the same time ;-)
I just found a more interesting subject ;-)

Imagine seeing on a shop poster "10 OFF" or "0.1 OFF" and you've got the answer to THAT point.

Can I extract from your snippy comment, that in your opinion we should omit the % sign because one can clearly distinguish between a pure ratio and a percent-scaled ratio?

What about the distinction between the percent-value and a value in degrees?
