What do you suggest would be the right time ?

Please note that the next major release of VMware's product will not
have this supported. Also that, most of our customers will actually be
running some distro's enterprise release, rather than running the
cutting edge kernel. So IMO there is still a window of around 1-1.5
years, until a customer actually sees a kernel which has dropped VMI
support.
