I don't think I can usefully respond to that. You're interested in Schmelzer's papers. The author has a colourful website <https://ilja-schmelzer.de/ https://ilja-schmelzer.de/> on which he solicits comment and provides an email link. I think you should feel reasonably welcome to send a brief initial hello and a couple of questions about his work. Additionally, he might have some ideas on your point (1), beyond the reference sections of his various papers. He might also have some thoughts on (2), which could turn out to be related to what I see as a remarkable contrast between his 1997 preprint's Discussion section and the final paragraph before Appendix A in his 2012 publication.
