Since you asked. I favor your approach -- just do it for me, the non-power user.

Remember those "turbo" buttons on old desktop PCs? For some reason,
you could "choose" to run them fast, but they would default to slow (I
am not talking about overclocking or any such nerdy thing... I am just
talking about a button that said "turbo.") I can't imagine why anyone
would want to run their desktop PCs slow on purpose...

Just make the indexes that will help me do my work faster and spare me
the details.

For those who may want more control, give them an opt out. I know this
increases your work to make this idiot-proof, but you asked for
opinions.

DWIM -- do what I mean, and I always mean faster.
