Indeed, sorry; I meant flycheck-pos-tip-hide-delay.

Isn't that one more burden that we impose on package developers for essentially 
no good reason? Also. what do you mean by "use the value by default"? Do you 
mean to initialize a defcustom? That won't work: changing the value of 
tooltip-hied-delay would not update that of the corresponding defcustom. Or do 
you mean that all packages using tooltips should explicitly pass a hide-delay 
argument to pos-tip or tooltip or x-show-tip, with that argument being (or 
package-local-delay tooltip-hide-delay)? That sounds cumbersome and error 
prone: if that's how we want things done, why is the delay argument optional?

In any case, do we gain anything from hardcoding 5 as the default?

Thanks for your opinion and responses! (and thanks Eli, too :)
