I think you're right. It can EITHER be a trickle-waterer, OR be a compost tea kettle, but probably not both.
If you flood a "compost-pipe" it would quickly wash out the tea that had been brewing by clinging to the compost. Then, the water that stays behind in the compost would resume making aerobic compost tea.
Probably if you filled your root-watering bottles with raw compost, the pinholes would clog up.
P.S. I find many shapes of plastic bottles in the recycle boxes at work. If your street has "recycle pickup days", you might browse those before the pickup time. Or find a local dump or Recycle Central, which we seem to call "transfer stations" here.
