I believe you have confused my comments with others. My comments have
focused on one aspect: The insistence by BPF maintainers that all code
bases and users constantly chase latest and greatest versions of
relevant S/W to use BPF - though I believe a lot of the tool chasing
stems from BTF. I am fairly certain I have been consistent in that theme
within this thread.

Your gdb / libbfd analogy misses the mark - by a lot. That analogy is
relevant for bpftool, not iproute2.
iproute2 can leverage libbpf for 3 or 4 tc modules and a few xdp hooks.
That is it, and it is a tiny percentage of the functionality in the package.
