All wallet software that I know of has migrated from JBOK to some form of deterministically derived keys. The first wallet with deterministic key derivation that I know was Armory around 2011-2012, and its scheme inspired BIP32, which formed the basis of many key generation standards that followed.

Developers of reputable wallets use a suitable source of randomness and will generate a key in the whole range available, not restricted to some arbitrary small range.
