Let's leave this to one side for the moment, because the next case

If there are only TFM files in the tree, then VMS will be as efficient
as any other system in locating a particular file; if the tree has
other files in it, then unacceptable delays may occur.  It was really
this area for which I was seeking clarification: is TDS defined in
such a way that there is a TFM tree, a TEX/LaTeX tree, and so on,
or are the trees conflated in some way?

It depends even more on what the TDS specifies!
