It was an known and expected downside.
But there is an upside too. For me it's actually a benefit, because it means
I'm less likely to called in the middle of the night because the web site when
someone entered some unusual parameters and caused a bad plan.
Whatever plan it's using when I test it will be the same as the plan it uses
for others, which may not be ideal but it won't be a surprise and I can
anticipate whether it'll be a reasonable plan in the future.
I can't anticipate all the potential plans the database might come up with for
all the possible parameters.
