Starting from the proof of the \(C^0\)-inextendibility of Schwarzschild by Sbierski, the past decade has seen renewed interest in showing low-regularity inextendibility for known spacetime models. Specifically, a lot of attention has been paid to FLRW spacetimes and there is an ever growing array of results in the literature. Apart from hoping to provide a concise summary of the state of the art we present an extension of work by Galloway and Ling on \(C^0\)-inextendibility of certain FLRW spacetimes within a subclass of spherically symmetric spacetimes, to \(C^0\)-inextendibility within a subclass of axisymmetric spacetimes. Notably our result works in the case of flat FLRW spacetimes with \(\alpha(t)\to 0\) for \(t\to 0^+\), a setting where other known \(C^0\)-inextendibility results for FLRW spacetimes due to Sbierski do not apply.
