Importance of Foreign Tax Credit (VTWAX vs VTSAX + VTIAX)

Hi there, I’m curious if anyone has a sense of the magnitude of the tax advantage one might be giving up by opting for the simplicity of a total world fund vs separating foreign and domestic funds in a taxable account.

I know the official PFC answer is probably that simplicity is best, but I’d like to hear how the PFC employees (or the community) choose to handle this personally in taxable accounts. Thanks!
