Why MySQL mysql table is still is MYISAM when InnoDB is encourage to use? -

i know why still version mysql server 5.6+

mysql store meta database('mysql') tables in myisam type when encourage developers/users use innodb default database engine , considered outdated use myisam anymore ?

of course no 1 can speak dev team, myisam seems appropriate choice these tables :

• no real need row-level locking: there little if need concurrency, since few threads (typically one: administrator) supposed ever write database @ time. table-level locking should suffice.
• very rare need transactions: typical access read-only
• little need support of foreign keys: structure trivial, mysql devs don't need safeguard maintain referential integrity (not you, smart administrator, not supposed fiddle database: administrative tools , commands exist reason)
• speed matter here: myisam still faster innodb, reads
• if ain't broke, don't fix it

i see 1 reason switch innodb though: its resistance crashes , ability recover one, due transactional nature.
