   The comment about extra data stuffed in scriptSigs was introduced in #4365 which introduced ScriptSigArgsExpected(), and became incorrect after #7387 / #7453 (checks are now performed by SCRIPT_VERIFY_CLEANSTACK during script validation and IsPushOnly() in IsStandardTx()). Drops the details on what a p2sh with many checksigs would look like, which was already done in #4365, but only for main.cpp not the duplicated comment in main.h, which was merged into policy/policy.cpp in #6335 and later moved to the right place in #10682.

   It’s still filtering other types of non-standard scripts, which also protects against the same issue of lots of operations (in addition to offering upgrade hooks)
