Since almost no one uses CRT monitors any longer, at least enabling subpixel rendering should be a safe and wise choice.
It is not safe legal wise, since Microsoft has still valid patents (until 2019) on subpixel hinting.
The only active patents AFAIK are on the color filter function used in ClearType. Even though it's quite likely that this is "obvious to someone skilled in the art", to the best of my knowledge this has not been challenged. But you need some sort of FIR filter (mathematical truths and the resulting algorithms can't be patented, although specific implementations may be patentable if they are clever enough) and the filter coefficients chosen for ClearType actually suck IMHO since they produce a lot of color fringing on LCD that can easily be avoided by chosing a slightly different roll-off. Subpixel rendering itself can't be patented due to prior art dating back at least to the Apple-II. Bytecode hinting patents (for TrueType IIRC) have expired in 2010 already.
