I understand, thanks.  But to me, such a global value makes very
little sense, because tooltips can be used for many different features
that don't necessary display short helpful text.  Having a single
value for all the possible use cases is IMO not a good customization
design, as it can never be a "one fits all" value anyway.

Once again, the current hard-coded value is not a global default, it's
the last resort that is clearly not meant to be used except in very
rare situations.  Developers of features that use tooltips via direct
calls to x-show-tip are encouraged to invest some serious thought into
how they want this aspect be customizable by their users, and provide
defcustom's as appropriate.  Alternatively, they could use
tooltip-show, as the documentation suggests, in which case the
defcustom's already present in tooltip.el will do.
