Форуми / Cotonti / Support / Replacing {PAGE_TEXT} with multiple extra fields.

I was talking to someone the other day and he suggested to use additional extra_fields to create a page text area.
By default we have this one big area of text where people write all the text they want to display on the page (wether using bbcode or html). So, instead of making one big area, what would happen if we use extra fields to create every specific part of a page with the specific text in it?

For example, site staff knows how to properly write pages, make additional subtitles on a page which contains specific info. However normal members do not know such a proper formatting and often submit a very messy page with wrong formatting. Sometimes they just do not know, they simply do not get it or they do not care at all.
So, to always preserve a page layout using extra fields which create the proper page layout for anyone who writes a new page could solve this.

However, I am not sure if we go this route what could happen and wether it might be bad for whatever reason.
Could it cause conflicts with the caching? What about SEO? Could it could issues with the database or with the load times of the website cause it is not optimised for such usage?

Just some questions I hope people can maybe answer cause I truly do not have any idea wether this might be a nice workaround or the worst idea ever presented.

Any thoughts on this?
