are you sure that all DNS implementations (both client and server) support this construct (client requests TXT record, server returns CNAME, client interprets CNAME, client requests TXT record for aliased domain)? AFAICS it's not violating any (DNS) standards...

That's what CNAMEs do. The indirection happens in the DNS cache, not the client. Any DNS that doesn't handle them would be utterly broken.
