Problem Description

I'm maintaining a H4AsyncTCP library after the passage of its author a year ago, and I'm heading to develop TLS by utilizing LwIP ALTCP raw APIs, which offers seamless shift out from raw TCP APIs code with the help of ALTCP TLS.

However, observed that ALTCP headers are not present within lwip library.

How would esp8266 arduino team observe this request?
What can someone proceed with ALTCP & using Arduino altogether?

With thanks,
