Inconsistent response of the native callTracer (difference in release-1.10 and release 1.11)

[alexqrid]

System information

Geth
Version: 1.11.1-stable

Description

There are some changes affecting native go call tracer.
I'm trying to trace the same transaction with geth 1.10.26 and geth 1.11.1 and receive different fields for DELEGATECALL.
Should value field make sense in DELEGATECALL?

Expected behaviour

No value field in `DELEGATECALL

Actual behaviour

There is an additional value field in DELEGATECALL

Steps to reproduce the behaviour
