Sure, but https is not the only protocol. tcpdump is also pretty useless at debugging OpenGL. https is only one protocol. There are hundreds or thousands of other protocols that tcpdump works fine with. Some of these protocols are underneath https, including tcp, which is in the name of the tool. So while tcpdump may not function as a tlsdump and can't see into your tls connection, it does a lot of other things great. You may as well complain that your screwdriver is no good for cutting wood. Clearly you need a different tool.
