Yes, the ABCs can be put together in one file; all the X-field numbers are distinct. (That's for those who may have interpreted your question literally.)

As for, "Will I compile the ABCs into a single file and put it in my repository?" I'll consider it, but my gut response is, "Probably not." Such a file would have to be maintained incrementally, and so would require extra work, while only a few people would actually benefit. Now that I'm providing MIDIs and PDFs as well as the posted ABCs, correspondingly fewer people have any need or desire to muck about with the ABC format (despite its many virtues). So applying the principle of diminishing returns and multiplying by the underappreciation factor....
