I am not sure that is for certain, with these private debt "facilities" (as the OP calls them). Seems like that's a big question.
Related (I am aware does not answer the question), the OP suggests this credit was pursued precisely because "increased regulations and capital requirements made it more challenging for traditional banks to issue certain types of loans."
>"increased regulations and capital requirements made it more challenging for traditional banks to issue certain types of loans."
Basel III requirements post-GFC made it expensive for banks to hold riskier loans so private credit was born.
While some regulations post the GFC were necessary, it seems like a bunch of the rules just pushed this risk (bad loans) onto the balance sheets of non-banks. Not sure if it was worth it, especially given the large hit to worldwide productivity.
