Creating outlines

I'm going to disagree a bit with an "always" policy of storing logos with text objects still active. There are plenty of hazards that exist with keeping the fonts active. One type family may have numerous versions, often sold by different vendors. Futura is one example. All these different "flavors" of Futura visually look the same at first glance. But if you set a text string in these different versions of Futura and line the objects over the top of each other you'll see all kinds of subtle differences. Even updates of the same type family from the same vendor can be different. The version of Arial bundled in Windows XP is far different from the one bundled in Windows 10. The same typeface may exist in different font formats, such as Postscript Type 1 or OpenType. I've seen old graphics files using "dead" font formats like Type 1 Multiple Master. Very few applications outside Illustrator can handle OpenType Variable fonts.

If someone is storing a logo file with text objects still active they'll either need to bundle the specific fonts used in the project with that logo file or make a very clear record of what was used -more than just the font name. Otherwise if the person opens a logo file 5-10 years later and doesn't remember what specific fonts were used the file can bascially "break" to varying degrees when re-opened. If other people are handling a logo file with active text then font substitutions will be very likely.

If active text objects are applied to paths, warped, etc that will also be a hazard over the long term. Even if the original fonts used in the project are installed newer versions of graphics applications can alter how they render type-specific effects, such as text on path effects. I haven't had many issues with text-based effects in Illustrator, but I've seen old files from other applications do all kinds of wacky, unpredictable things when re-opened many years and many product versions later.

For long term archiving purposes at least one version of the logo needs to be saved with all type converted to outlines and any other "live" effects expanded into editable vector paths. A properly finalized logo design should be portable to other rival graphics applications. That port-ability is compromised when a logo or graphics element uses unique features dependent on a specific application or application plug-in.
