Baritone / Schematics / Build Command

So I have more or less 3 questions which I hope didnt get answered already.

- Is there a plan to somehow support the build command/schematics in 1.14 or are there plans for 1.15 to somehow work with older builds due to I think changed block IDs in older schematics or so, not sure.

- Is there a way for Baritone to tell which blocks are needed + how much times for a build?

- Is it possible to pause/resume the build command to refill the blocks if you are in survival and let it resume from the old position? If not would the last 2 be a possible thing which would come in the near future or probably not?

The issue discusses Baritone's build command and schematics, but names no files, tests, or entry points. Start by locating the build-command and schematic implementations, then determine whether version compatibility, block-material counting, and pause/resume behavior are separate feasible changes. Done would require agreed scope and tests for each selected capability.
