Even if the module was hit by a PTF, it's a lot easier to start with the optional source than with the microfiche.
for the code written in PL/S (nee BSL), the optional source has the generated assembler with the source PL/S as comments; I found that reasonably easy to work with even though I would rather have had a PL/S compiler. -- Shmuel (Seymour J.)

For the base it was not uncommon. But while PTF source was, in theory, RPQable, in the real world no one had complete source matching the MVS they were actually running at any given time. And of course there's another argument to be had over whether source in a language for which no compiler was generally available counts as Open Source.
