I do agree, and there were requests as well offlist/offbts on this, though we won't enable it anymore at this stage of the bullseye release preparations for bullseye but will follow in a later experimental upload.

Bug#987815: MPTCP is not enabled
Source: linux Version: 5.10.28-1 Severity: wishlist The current configuration does not enable the multipath TCP functionality provided by the kernel through the MPTCP (and the the-default MPTCP_IPV6) binary options. These have been available since kernel version 5.6. When enabled, user space applications can opt in to MPTCP behavior by using the new IPPROTO_MPTCP; regular TCP connections are unaffected. Applications using this are starting slowly (outside of the Apple ecosystem where this has been in used for years to ensure smooth network handovers), but having this available widely would make it easier for application developers to verify MPTCP operation on systems where they can't easily (or don't have the experience to) rebuild their kernel with CONFIG_MPTCP=y.
