Discrepencies vs spec and `NodeTemplatePart`

[keithamus]

One other thing I see discrepancy with is missing NodeValueSetter in NodeTemplatePart. I get your reasoning - it also seems a bit faster to not have setter and call splitText in collecting parts instead of initial replacing with collected parts, but I wonder if nodePart.replacementNodes can be useful for processor implementors - it seems to be missing now.

  // NodeTemplatePart
++  get replacementNodes() {
++    return this.#parts
++  }
