Hmm, interesting question. On the hand JITs do devirtualization, so that on lots of code paths the indirect calls are replaced with direct ones. Which should mitigate the performance issues. However I think the JITs also need to insert the logic and branches for re-jitting and spectreulative execution. These might be additional indirect calls.
Would be interesting how it balances out in total.
