Do Order of the Scribes wizards have reduced spell learning GP costs?

The Player’s Handbook uses the following language to explain how wizards obtain spells:

Copying a Spell into the Book. When you find a wizard spell of 1st level or higher, you can add it to your spellbook if it is of a spell level you can prepare and if you can spare the time to decipher and copy it.

Copying that spell into your spellbook involves reproducing the basic form of the spell, then deciphering the unique system of notation used by the wizard who wrote it. You must practice the spell until you understand the sounds or gestures required, then transcribe it into your spellbook using your own notation.

For each level of the spell, the process takes 2 hours and costs 50 gp. The cost represents material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it. Once you have spent this time and money, you can prepare the spell just like your other spells.

The "Wizardly Quill" ability in the Unearthed Arcana that first described Order of the Scribes wizards used the following language:

• The quill doesn’t require ink. When you write with it, it produces ink in a color of your choice on the writing surface.

• The gold and time you must spend to copy a spell into your spellbook are halved if you use the quill for the transcription.

In the final release of the class through Tasha’s Cauldron of Everything, the language has changed to the following:

• The quill doesn’t require ink. When you write with it, it produces ink in a color of your choice on the writing surface.

• The time you must spend to copy a spell into your spellbook equals 2 minutes per spell level if you use the quill for the transcription.

There are, it seems, at least two interpretations of how this affects spell learning costs:

  1. Wizardly Quill does not say anything about the GP cost of learning spells, and therefore, the costs remain unchanged.
  2. Wizardly Quill reduces the cost of ink to 0 GP. Spells cost 50 GP/level when learning spells that require costly material components (e.g. Find Familiar). Spells cost 0 GP/level when learning spells whose material components are substituted by an arcane focus (e.g. Feather Fall).

My inclination, based on the Rule of Specificity, is to rule for the first option.
