Yes, it should all remain backward-compatible, at least unless and until
some maintainer leads a two year campaign for migration to a different
setting.

My plan is as follows:
1- have a special variable tell whether to recurse under a .asd by default,
defaulting to t for now
2- adding some keyword argument to :tree to override this variable
3- adding support for source-registry.conf and/or .source-registry.conf as
things to detect and heed when recursing into a directory.

I modified my previously posted code as a solution for 1, attached.
2 and 3, I'll add to the TODO for now.

(And yes, changing startup from 1.45s to .66s with cl-launch (resp. .83s to
.33s without) is well worth it. It makes some scripts usable that are
otherwise annoyingly slow; the difference is even more dramatic for me on
CCL, where it drops from 2.57s to 0.37s with cl-launch (resp. 2.0s to 0.27s
without).)

PS: while testing my changes, I found a trivial bug in test-program, that
failed to rename load-fasl-op to load-bundle-op. Fixed.

        Said the fly: "let us flee!".

So they flew thru a flaw in the flue...
