Honestly I can help but be intrigued by "PoL" and given all the build up Oda gave it on Egghead I do really hope he expatiates on it this arc.
A strong theme of Egghead was that "love overcomes all and has no limits" (i.e. "Love has no limits", "Love doesn't hold a candle to light" etc.) so I'm really intrigued at the possiblities of this ability.
Fact that Oda gave Sanji a lot of focus with this ability on Egghead, assosciated it with the Buccaneers and chose to not delve into it is very intriguing.
Even more so when you consider the Garp situation, I'm still skeptical about Garp being a PoL user but Oda making a distinction between Haki and Love in the SBS is also pretty intriguing.
Hence why I strongly think that Oda will be building on this going forward with Sanji.
Also I went back to read the fake Einstein letter about PoL which is clearly what Oda is being used as a motif for this ability in One Piece and I noticed something pretty interesting.
This is an exerpt of the letter.
There is an extremely powerful force that, so far, science has not found a formal explanation to. It is a force that includes and governs all others, and is even behind any phenomenon operating in the universe and has not yet been identified by us.
This universal force is LOVE.
When scientists looked for a unified theory of the universe they forgot the most powerful unseen force.
Love is Light, that enlightens those who give and receive it.
Love is gravity, because it makes some people feel attracted to others.
Love is power, because it multiplies the best we have, and allows humanity not to be extinguished in their blind selfishness. Love unfolds and reveals.
For love we live and die.
Love is God and God is Love.
This force explains everything and gives meaning to life. This is the variable that we have ignored for too long, maybe because we are afraid of love because it is the only energy in the universe that man has not learned to drive at will.
One thing I though twas really interesting are these two statments.
```

```
```
Love is gravity, because it makes some people feel attracted to others.
```
Doesn't it seem like Oda is replicating these statements with feats? or am I tripping lol?
If the above isn't just a coincidence, we might get an insane raw power feat from Sanji this arc to match the statment below, which is very interesting given this is a giant themeed arc.
```
Love is power, because it multiplies the best we have, and allows humanity not to be extinguished in their blind selfishness. Love unfolds and reveals.
```
The "Love is God and God is Love" part is also very intriguing
