I ask: "how to react Rhino to the absence of two important plug-in?"

Rhino Rhino for Windows

Simple curiosity: the plug-in TSplines will no longer be supported and, in this case, Rhino is developing its SubD. Similarly, the plug-in VSR can no longer be used in Rhino 6. In this case, what you’ll be developing in its place?
Will we ever see most convincing tools, such as: a blend surface, a match srf, a Multiblend (very useful), a flange tool, and much more?

Many users made use of this very useful plug-ins, and now what will happen in the new version of Rhino?

I am going to run V5 as long as I can. Then when problems arise I hope I can get some help from smarter people than me ,right here. ----Mark
