Jan 8, 2023 at 0:38 comment added saolof Stupid question: how does the formalism prevent you from building the bug-eyed line while staying in CGWH? I assume this is what the closed space inclusion requirement is for?
Nov 30, 2022 at 9:23 comment added FShrike CGWH should have all pushouts, not just those with one leg a subspace inclusion, according to an exposition by Strickland. MacLane also claims CGHaus is cocomplete, in CWM, which is seemingly at odds with what you say here.

CHG would be "compact hausdorff generated" instead of "compactly-generated hausdorff" - this is a case where the letter order matters
Jun 5, 2019 at 15:52 comment added nrkm Can I ask for a simple counterexample of bad pushouts in CG Hausdorff category?

Apr 29, 2015 at 13:48 comment added Clément de Seguins Pazzis As far as geometric realizations of simplicial spaces are concerned, it turns that they are well-behaved with respect to the CGH property: see my article sciencedirect.com/science/article/pii/S0166864113002356. Yet, the concern over pushouts remains valid.
