It is "experimental" in the sense that a developer who is interested
in making the feature work end-to-end for the first time can use the
code behind the flag to prepare loose objects to prepare what is to
be transferred; it sounds more like this one is "not working yet" ...

... as the only end-user-perceivable purpose the compat format
serves is to exchange data between two repositories that use
different hash functions, no?

The word "experimental" to me implies that it at least lets you
complete a minimum end-user journey of the feature end-to-end.

There are different degree of experimental in this project and we
may want to do something about it, but in any case this is a welcome
change in the right direction to steer those with mere curiosity
away from hurting themselves.

    Note that the functionality hidden behind this extension is
    incomplete and the extension exists solely to allow us to
    continue developping it further.

might give them a stronger discouragement?
