The discussions online these days about capacitors, in general, borders on uninformed hysteria.
If the value is within tolerance and the ESR is reasonable, there is no reason not to use them in a hobby project. My exceptions would be electrolytics stored at high temperatures, which will of course dry out and lose capacity or anything over 50-100V since things can get violent should they rupture.
I routinely read about people ripping perfectly fine electrolytics out of otherwise inoperable gear without one seconds worth of investigation. Given their experience level, you know it will never be repaired because they will undoubtedly do more damage removing the old caps than had they left things as-is and spent some time doing a good visual inspection and then actually troubleshooting.
