Are you sure this will work correctly when the extension calls the 
substituteMarkerArray function (or comparable functions) multiple times 
in various stages of building the output (e.g. nested subtemplates)?

Any hook will decrease performance a little.

Extension authors need to be encouraged to make their extensions more 
flexible in this area.

It's quite easy to supply stdWrap support for each field in the db 
records inside the Typoscript configuration:

listView {
	field1_stdWrap {
		....
	}
}

And it's also quite easy to support extra markers in the Typoscript 
configuration:

listView {
	markers {
		marker1 {
			....
		}
	}
}

The extension only needs to use a few extra lines of code to add this 
flexibility.
