Snapshots are usually fairly stable and directly from the git master is also usually stable though there are occasionally short periods of time when a major addition can create stability issues. We usually fix any instability very quickly. Many people use the latest development release as their primary simulator.

LXT2 certainly will not support this and I don't know if the latest VCD specification has enhancements to support this or not. It may not be too complicated to add this to the run time, but like I said earlier often things can get more complicated than expected.
