If the party is focused on creating circumstances for the thief, then those circumstances happened more often--especially with invisibility potions/rings/spells.
Most fights in my games made the thief a tertiary combatant (behind the cleric or druid), or dead last (if the magic-user was involved in the fight with spells or summoned monsters). For combat-light adventures, no big deal.
In any case, most of the players in my games played thieves as "rogues" (unconventional types, good with their hands, good at getting by in tough scrapes), not as actual thieves (criminals that steal things).
Of course, some folks don't like the term "wizard" for a class name, since that is the "name level title" for an accomplished magic-user.
