True. In fact even XE & XR BGP code core is quite different in spite of
number of failed
attempts to at least make new bgp features to share code.

The bottom line is that if you get badly malformed update, broken
attribute, illegal NLRIs, mistaken blast of BGP-LS etc .. the probability
that all of those BGP implementations crash is much less likely then when
compared that your chosen one will work even if you run two instances of
it.
