So far, it has proven to be an acceptable price to pay for innovation. Yes,
it causes some pain, but if we fix the APIs between major releases, this
will be the start of the end for Drupal, since it will either get bloated by
a compatibility layer (more resources, slow, complexity, ...etc.), or Drupal
will stagnate and no longer become a leading content management

Having said that, there is nothing stopping YOU (or others) from building a
compatibility layers. Some people tried that from Drupal 4.6 to 4.7 after
Form API was in core. We just don't want that to be in core.

Better focus on tools that would make migrating your modules easier/quicker
(core, deadwood, documentation for converting from 6.x to 7.x, ...etc.)
