As people become more familiar with Oxy 5575 turning out to be a 2nd century harmonization of sayings exclusive in extant sources in the Gospel of Thomas with canonical sayings, one detail should rightfully change how people moving forward look at the Gospel of Thomas itself:
There's no "Jesus said" before different sayings.
For a while, a personal theory was that these separators in Thomas were a later addition, but there was no sayings source absent them to back that up.
You can see in Thomas places where adjacent sayings ended up combined (saying 110 seems to combine saying 80 and 81).
And you can also see places where seemingly connected fragments of sayings are split apart by "Jesus said" such as saying 18 to the first part of 19:
18. The disciples said to Jesus, "Tell us, how will our end come?"
Jesus said, "Have you found the beginning, then, that you are looking for the end? You see, the end will be where the beginning is.
Congratulations to the one who stands at the beginning: that one will know the end and will not taste death."
19. Jesus said, "Congratulations to the one who came into being before coming into being. [...]
About a year ago I removed the "Jesus said" separators and reviewed the text again, seeing that a handful of adjacent sayings seemed to have a newfound connected train of thought, but the arbitrary numbering (largely predicted on the "Jesus said" separations) were leading to treating potentially connected sayings as distinct from each other.
If a 2nd century form of a sayings work did not have those separators between sayings, review of 3rd century copies of Thomas should engage more with the notion an earlier form of that document was also missing the separation and grouping that's found in it today, especially considering the combinations and odd separations the extant document showcases.
Just 2¢ from someone that's been closely looking at it for a few years now in light of the recent find...
