I do burry the standard 1.5L plastic soda bottles as well, with loads of holes in the sides and upside down without the cap (think it is the most practised diy watering solution for tomatoes), but there are always bottles that remain half full as the end of the season nears. I have heavy soil that can become hard as a brick in summer, that soil might be more prone to cluttering whatever device you use; Sticking textiles through the holes could preserve the permeability (the "wick" strategy) but I don't like to buy laces or tear t-shirts for that - don't think it's durable and I would need material for 42 bottles ...
Chances are that plants still can suck up water from the bottles that seem cluttered but still I use my wine bottles as an 'always delivering' backup.
