I wouldn't be entirely opposed to having an abstract configuration class, but I hate to switch the configuration structure in midstream again... it is very nice that a config can be loaded into any old smalltalk image without any prerequisites....

The #ensureMetacello method should simply load ConfigurationOfMetacello and go from there ...

To require an abstract configuration class, I would want that class to be in the core for Pharo, GemStone and Squeak ... Metacello is already bundled with the core in GemStone so that leaves Squeak ... I really don't want to have to preface all of the install instructions with "Before loading the configuration, make sure that you've done X, Y and Z"

If bootstrapping is the only consideration, I don't think it is worth making the change ... there isn't a lot protocol that I would want to put into the Abstract configuration class ... project instance variable and method ...

If there are enough other arguments for an Abstract configuration class, then it would be good to make the switch sooner rather than later.

Being able to view the configurations using a hierarchy browser is an advantage, but that's more of a tools issue.

As I think about it, most of the advantages that come to mind are tools related. Even bootstrapping is a tools issue of sorts...

What do others think?
