What problem does this solve?

A clear and concise description of what problem this feature would solve. For example:

• I am suggesting the FilePath option in all flags should be converted to a string array.

Solution description

A detailed description of what you want to happen.

Today, the FilePath option for all flags is a string. You can use it as an array by doing comma-separated paths within the field. In v1 EnvVar and FilePath were consistent where you could specify an array of environment names separated by commas. I believe the value in converting FilePath to a string array is to maintain consistency for the users setting defaults on the flag options.

Describe alternatives you've considered

A clear and concise description of any alternative solutions or features you've considered.

Another option I see is leaving it the way it is but one could argue the user experience isn't consistent between setting config for EnvVar and FilePath.

@kneal do you have any examples that utilize this behavior? Since this is a breaking change I would likely target for v3
