The reason that simply execing pcregrep is insufficient is because it is not GNU grep, and is not compatible with some other command-line options of GNU grep, so having GNU grep execute it when -P is given, would break compatibility with other systems that use GNU grep, just as disabling -P has. The right solution is to include the tiny PCRE library in /lib so that a core utility (grep) can behave the same on all platforms.
