Several interpreters and compilers take a long time to build today.
This may change, of course, after another generation of hardware is
released.

No difference for you perhaps but that is an important difference to
many of us.

That would violate the principle of least surprise.  If the same command
used with one port compiles from source but when used from another port
downloads a pre-built binary that's to be avoided (whether or not some
java ports already do this).

If we're talking about Poudriere then please first consider better
build-time optimizations than downloading binaries that may have
security implications and will change over time.

Tangent: If we're talking about additional make (not pkg) functionality
then please add a constant to only create packages, for the target app
and all dependencies, and install them only using pkg (the OpenBSD
model).
