It was real, working code.  The only thing that was missing was uniform
way to take advantage of the new structure in the user commands to find
files, grep strings and run compilation commands.  Also, the follow-up
message showed that it's possible to have the new logic and not use any
internal data structures "from the outside".

I don't think it has to be so extreme.  I don't understand why there
isn't a user-callable construtor for a type of project that is currently
represented by the '(transient . "<dir>") implementation detail.
Demanding that the users of looking to add to project-find-functions
additionally define a whole new type and all the operations to go with
it is unreasonable, IMO.  I don't think it's "throwing away the whole
design" to provide one such constructor or a means to simplify this.

Even better, provide a CLOS class, so that users may subclass it and use
inheritance in the CLOS generics.
