Even if a module is "bundled", that doesn't mean it automatically becomes available to all vanilla builds of PHP. I know that a lot of Linux distributions break up their PHP packages so that pretty much every module can be installed separately; conversely, they provide pre-compiled packages for a lot of PECL and third-party extensions. So there's very little difference between installing, for example, "php-zip" (bundled) and "php-redis" (PECL). I glanced at a couple of the WordPress hosts you mentioned, and couldn't find a clear description of their PHP configurations, but I suspect it's similar - some "bundled" extensions won't be enabled (e.g. various database drivers), and some PECL extensions will be installed as standard (e.g. Redis). In practice, I think there are four types of extension, not two: A) Core, and either can't be disabled, or disabling is very rare B) Bundled, but optional; may be packaged separately; may be optional or not supported by managed hosting C) Not bundled, but widely available pre-built as well as through PECL; may be included or available in managed hosting D) Not bundled, and not widely pre-built; mostly available only via PECL Type B and C enjoy similar availability to users, but type C allows a package maintainer more freedom to maintain and evolve the extension; type B trades that for a rubber-stamp of official approval.
