The grounds crew etc. would have to be completely on call, not to mention ticket sales would be a mess. And the Tigers wouldn't have known until late last night whether they were staying put or traveling. I think they definitely have to know who has home-field advantage before the postseason begins.
Knowing who has home-field advantage isn't a big issue for the Division Playoffs or the LCS. They have two days between the end of the season and the start of the playoffs and sometimes two days between the end of one playoff series and the start of another. They often don't know who is hosting the games until the last minute. The grounds crew, ticket sales, travel, and everything else you mentioned are affected the same way for every playoff series. They cope. They make contingency plans and they cope.
The NHL and NBA both deal with the same issues (groundskeeping notwithstanding in the NBA). They cope, too.
The World Series doesn't have to be different. It *shouldn't* be different.
