I've used an expanded secondary skills list in my BASIC and 2e games, and I've never really had a problem with people overreaching with skills. So what if a bounty hunter wants to say he is good at picking locks and finding traps as a bounty hunter? Unless there is another party member named Zook Gnomeboots Troubleshooter and Trapmaster of the Locksmith's guild (and the bounty hunter is trying to steal his thunder) then why can't he try to pick the occassional lock?
D&D needs every incentive it can get to encourage players to engage with their campaign world and seek solutions over obstacles besides bashing it down or killing it. In my basic game we are playing in the wilderness. I have a party of three, a mage, a dwarf, and a thief. The dwarf is an old soldier who learned how to track in the underdark using his infravision, so he shields his eyes and does the party's tracking. The mage is a sage so he covers the knowledge skills including herb-lore, and the thief uses his natural stealth to do the scouting and hunting. Between the three of them, they have the skills needed to get along in the wild, even though they don't have a druid or ranger.
According to this thread I'm letting the PC's get away with too much. But you know what? It's fine. It works. It keeps the plot moving. The explanations are plausible enough for vermisilitude, and the game balance is perfectly intact.
