In a discussion on the bitcoin-dev mailing list, Eric Voskuil corrected a misinterpretation of BIP30, stating that duplicate transaction hashes can and will happen in Bitcoin even with the activation of BIP34.
He explained that BIP30 was given similar treatment after a reasonable amount of time had passed and provided a link to the relevant code in Github. Another member of the discussion, Jorge Timón, clarified that blocks complying with BIP34 will always necessarily comply with BIP30 because coinbases cannot be duplicated after they include the block height.
