I'm concerned that using Tika would double the size of JMeter.
Although the extra features would be useful, I suspect that most test
cases won't need the extra functionality.

Would it be possible to make the Tika jars optional?
i.e. add the functionality, but if the jars are not present it is disabled.

If we accept that developers must download Tika, then it should be
easy enough to structure the add-on so that JMeter can fail gracefully
if the jars are missing.
But ideally developers would not need to download all the jars either.
