PSA-If you are waiting for a good time to buy incubators...now is probably the time
It has been noted here and on the Silph road the egg chances per research.
Even if you think that eggs have a strong biome tie or whatever your chances of drawing a "good pull" from eggs is unlikely to get better. With the starters ready to get dropped at whatever rarity among others the hard to get mons can only get more rare. There are no mons withheld from eggs that fall in this catagory. So if Silph road research is correct there cannot be a better time to invest unless legendary mons get dropped into eggs out of nowhere.
Thoughts?

while 5km egg is really useless.
Not so. There are just more possibilities. But 5km eggs have many useful hatches, especially if you look long term. They give you Rhyhorn, Porygon (a rare mon for the Pokedex and also one whose candies will be needed for the very good Porygon-Z), Lickitung (also rare and whose candies will similarly be needed for Lickilicky), Phanpy (Donphan is one of the best mons to come from Gen 2), Smoochum (Jynx is now very viable with Avalanche as a charge move), Elekid (will need its candies for Electivire), Magby (will need its candies for Magmortar), Eevee, Tangela, Scyther (needed to evolve Scizor), Onix (needed to evolve Steelix), Omanyte, Sandshrew (Sandslash is an underrated good attacker and great prestiger), Staryu (Starmie with Water Gun/Hydro Pump is very good), Grimer (very, very rare, and Muk can be useful), Magnemite (will need its candies for Magnezone), Shellder (Cloyster is a great Dragonite killer), Poliwag (Poliwrath with fighter moves is strong against Tyranitar), etc.
2km and 10km eggs are very useful
2km eggs contain plenty of junk too (Goldeen, Krabby, male and female Nidoran, Diglett, Ekans, Remoraid, Slugma, etc.). And there are a few questionable 10 km egg hatches also (e.g., Mantine, Skarmory, Sudowoodo).

I am getting a huge number of Chansey too.
I also think there is a (weaker than often implied) tie to biome but I'll admit I think it exists. But, sidestepping that discussion, the fact you can get Chansey reliably until the Mon draw gets watered down with garbage supports my OP. There may be no better time to invest.
