Well, you try for one thing to avoid using them unless you've got the Pico soldered down to something that breaks them out to pins, like Gordon's Wiznet shim https://www.tindie.com/products/gfwilliams/espruino-pico-wiznet-w550io-ethernet-shim/ , or my Espruino project board https://www.tindie.com/products/DrAzzy/espruino-pico-protoboard-discount/
Or, you might use the ESP8266 shim https://www.tindie.com/products/gfwilliams/espruino-pico-esp8266-wifi-shim/ and use the ESP8266 instead.
You can get 0.05" pin header, but that's not much easier to work with.
