The above feature was quite new (2.5?) where you can add custom rules
to subdir without replacing it, as well as some bug fixes. Whilst bjam
has had some mods applied, last time I looked at bjam it was behind
and didn't some of the bug fixes so I came to favour the stock
version. Use whatever works for you I suppose. bjam's strength is that
it comes with a very complete set of rules for building portable
projects. But you seem to be using the stock rules not the boost
rules, that's why I said it.

Nothing wrong with the stock version if you have a small/medium
project to build. A larger project will probably just need a few mods
added, depending on how you stress it.

There is also jamplus which has whole bunch of mods that Joshua & Alen
have put together with a number of interesting features.
