Right now LSB 2.0 is in public review. (Beta/release candidate)

1.x have some severe restrictions that has really factionalized (not fractionalized) the Linux Community.

Debian should be the most LSB compliant and it doesn't even come close. Most of the 1.x LSB was pushed by Vendor driven certification, without any regard for flexibility.

LSB2.0 make some serious progress in this regard. Restriction, with exceptions and alternate sets of restrictions but still also requiring the standard spec to be "there" be it in symlink or hardlink or other means. This will allow many more Distros to actually make the LSB standard.

LSB may end up being irrelevant anyway. As there are bigger things to worry about in terms of interoperability. But then again, if someone finally takes the LSB seriously as a Real effort to embrace and follow the "standards" it may just end up help the Commercial Unices as well.
