That seems worse? considering it's not using the glob patterns set in main.ts, and will ignore any MDX files not following the .stories.mdx pattern.

Alright sounds good, maybe the other automigration should follow this pattern then

const val = await acc;

if (val === true) {
return true;
}

const pattern =
typeof item === 'string'
? slash(join(configDir, item))
: slash(join(configDir, item.directory, item.files));

const files = await glob(pattern);

return files.some((f) => f.endsWith('.mdx'));
}, Promise.resolve(false));

const usesMDX1 = mainConfig?.features?.legacyMdx1 === true || false;
const skip =
usesMDX1 ||
!hasMDXFiles ||
!!mainConfig.addons?.find((item) => {
if (item === '@storybook/addon-mdx-gfm') {
return true;
