No, perhaps it is for people that don't understand what a parlay bet is. Let me break down why your bet was a mistake at the start.
A six team parlay where all selections are -110 (1.91) is this:
Bet #1 $350 to win $318.18 (On win have $350+$318.18=$668.18)
Bet #2 $668.18 to win $607.44 (on win have $668.18+$607.44=$1275.62)
Bet #3 $1275.62 to win $1159.65 (on a win have $2435.27)
Bet #4 $2435.27 to win $2213.88 (on win have $4649.15)
Bet #5 $4649.15 to win $4226.50 (on a win have 8875.65)
Bet #6 $8875.65 to win $8068.77
Win all six and you have $16944 of which $350 was stake and $16,594 profit.
Now for yours all selections were probably not -110 which is why it is less. But what I'm pointing out is the same.
Understand all a parlay bet is, is a wager where your stake + win keeps getting rolled forward to the next play.
So adding another team you're going to hedge accomplishes nothing but locking in less money than you would have been paid if you didn't add that selection in the first place.
Back to my example:
Bet #5 $4649.15 to win $4226.50 (on a win have 8875.65)
At this point we had $8875.65. But we added another play of:
Bet #6 $8875.65 to win $8068.77
So to hedge this what we end up doing here is betting other side at -110 too staking $8875.65 so we have $16,944.42 return regardless who wins. Now in this case we've staked $350+$8875.65= $9,225.65. Our profit is $16,944.42 - $9,225.65 = -$7,718.77.
Again backing up to bet #5. Had we had never added team #6 we'd of had $8875.65 - $350 stake = $8,525.65
So by adding a team you didn't want to a $350 parlay and doing a 6 team parlay instead of a 5 team parlay without that team, you piss away $806.88 for absolutely no reason, other than lacked understanding of how parlays work.
So to answer your question no absolutely not standard to anyone who understands the very basics of betting - it is the opposite - foolish is adding that team in the first place.
Now to answer should you hedge for this specific play? - this is covered in the FAQ that is stickied. The important thing to gain from this is do not add teams you don't want to parlays in the first place. You would get paid more by simply never having them included than to include them and turn around hedging when it makes it to the end.
