As long as the vyper version installed and the one specified in the file pragma are the same, then, we can assume that there have been no breaking changes to the way in which vyper parses the AST and continue.
Currently, the behavior is that blackadder fails as the underlying vyper parsing functions fail due to the version mismatch. Hence, blackadder only effectively supports parsing files whose version pragma is the same as the vyper version installed currently
