It is technically feasible and certainly easy. But will the current programmers will one day contribute to Sage? If the answer is no, it would be bad to include it in Sage source code as it will diverge from upstream. This is why I asked to ask before moving on.

From a quick lookover, it looks like it is easy enough to actually port the
methods directly into Sage, which would make it easier to maintain and use
than an optional spkg.

Best,

Not short term plans as far as I know. The best would be to ask Thierry
Coulbois himself. One thing which should be relatively easy would be to
polish the doctests and make it an optional package.

Nifty! Any plans to include this in the code base?

Hello,

Let me tell you that T. Coulbois already implemented Bestvina-Handel
algorithm (for general automorphisms of the free group):

There are a lot of possible optimization and improvement in the
documentation. But it works well (and has been intensively tested).
