We have that today already today.  So yeah :)

The difference today is that my matrix plugin dynamically generates actual
tasks.  So assuming you had those profiles on your system you'd get dynamic
tasks: matrix_mysql, matrix_h2, matrix_mssql.  You'd also have a task
`matrix` that runs all of those.

The rub is that we actually do not leverage this today.  Today every single
build runs just one profile.  If we are going to allow running multiple
profiles at the same time, I personally think the matrix and dynamic tasks
are the better option.  So really I was more asking a question I guess
whether anyone plans on using that capability :)  Because to run just one
profile, the matrix add a lot of complexity that is probably just not
