The "must be optional" bit is discussed at [1] as well but MPL is not
affected by it - it is ok to have dependencies on MPL stuff as long as
those dependencies are to an MPL binary, as opposed to MPL source code
(see [1] for why that is so) and as long as that dependency is
"appropriately labeled".

IMO, running compiler tests falls into the "build tools" category
which is also addressed at [1], and which has less restrictions than
dependencies that are required to *run* our product.

Yes, it is ok to distribute a binary MPL dependency as a convenience
(like an additional -deps archive), as long as the Flex source release
that we vote on does not contain such binaries.
