Well "root" is simply the root folder of a TDS-compliant directory.

Well no. TEXMFLOCAL is a variable. Like TEXMF. The content of this
variable can be the path of the root of _one_ texmf-tree, but -- as
it is the case of TEXMF -- it can also point to more than one
texmf-tree.

Well certainly I can. I did it and it worked fine, my home made
luatex could used the various texmf-trees without problems.

But this is the interface miktex provides: In the GUI you see a list
of the actual texmf-trees. You can add a new one, move them up and
down (not every order is possible, the order of the trees installed
by miktex is fixed), and you can remove local roots. To use a Linux
wording: You can mount and unmount texmf-trees.

This is not asked for. miktex will complain if a directory is "not a
TDS-compliant root" is you try to "mount" an arbitrary folder. And
files will not be found if their are not in the correct
TDS-subfolder.
