I try to avoid the same bye weeks for starters in the same position. Like if my WR1 has a bye in 3, if I'm choosing between two WR2s that are in the same tier, a different bye week would be a tiebreaker.
To answer your question, I think the FF season is too short to dump 1 or 2 weeks to gain a small advantage for 5 others. There's a lot of random things that happen during a year--your RB1 sits a second half and you lose a game by a point, other guy's D returns a TD and you lose by a couple of points, etc--that you can't risk 15% of your season as "known losses".
On the other hand, if you're in an established league that you know is active--the rare league where the owners wheel and deal trades all season long, you can sometimes "sell short" on bye weeks. You can trade a player who hasn't had his bye for an equal player at the same position who has. This allows you to bypass having to sit your WR1, and the other owner will have to sit his WR1 twice--the player he traded away and the player he receives both have their byes while on his team. But trading players 1-for-1 in the same roster position, a WR-for-WR or RB-for-RB trade, is very difficult to accomplish. You have to know going into the draft that the other owners are the type to easily make this kind of rare trade.
Personally, I think you're better off in the long run all the way around by drafting quality backups, especially mid-round WRs. That position especially has a lot of variance, even among the top guys there are the 75-yard, no-TD games once in a while. If your top backup WR is good enough to start two to four games a year, you should be fine. If you're lucky you'll pick up 2 or 3 WRs in the WR25-45 range and one will hit a big season, playing at WR15 or so, and you can trade him or your WR2 and solve your byes that way and get great value in return.
