Currently, we check the feature flag for internal transactions twice when committing a transaction (once to decide if we should add the txnRetryCounter to the applyOps oplog entry and once to decide if we should add the txnRetryCounter to the config.transactions entry) and the FCV can change between those checks, and this can cause the config.transactions entry on the primary to be inconsistent with the config.transactions entries on secondaries.
