I've tested the EPG in different images,
there is definitely no ideal solution for EPG
except one more memory
all other solutions is the compromise.
BH clean image without major extras
can accept at least 4 providers.
I have test with all providers in one 26 mb Epg.dat
no crash but problems with stability
fror example System menu
lack of memory.
Of course, the more installed plugins/addons in the image , less memory
for EPG
So the users have to decide which are priorities for them.
Memory is not a bottomless pot
only if it is so great that you have no problems
Some images force the EPG in to memory
and do not give a chance to enigma to clean memory/remove epg
preventing crash and
result of this is the instability of the image,
or endless reboot/reload with to much epg.
Conclusion:
So choose a few most important providers
and doe not make unnecessarily epg updates.
Of course, limiting the size of the EPG
(limiting the number of days)
for some of you would be straightforward solution
but I'm not coder for epg data and image epg
so I do not know whether it is easy to make.

In connection to the servers problems we will have good news.
Very soon.
