Found an interesting review of the market posted on the FreeRTOS pages, produced by EETimes last year.The Embedded Markets Study 2019 shows 4% of developers are considering Zilog Z80 family for their next 16 bit project, and 5% are considering it for their next 8 bit project.But, it looks like no developers are currently using Zilog Z80 family, if I'm reading correctly. That seems like an incongruous set of views.
